Defender Td5 Running issues!

hi all - my 110 Td5 lost power the other night - i still got home but it felt like it was miss firing. next drove to work and back and it was the same - an hour later i started it to go out and it ran for 30secs then cut out and wouldnt start. i have done the following.

new injector loom
cleaned the ecu and the red plug (there was oil)

now starts on the button but runs rough as a badger!?!

what next? any help would be great.

Hi you really want to see if there’s any fault codes showing do you have a Nanocom?

i dont no - but your right that would be useful

fixed! turns out it was the loom and oil at the ecu - it was running on 4 cylinders as on number three the two wires were not fully click into the conector.

now runs better then ever and a lot smoother than it was before.

HALF FIXED!! after a few days she is still running smooth but no will not go over 50mph? if i push her to 50 the engine then runs like crap, what have i missed????

There might be residual oil in the wiring loom that has the red plug on it. Continue to clean it out for the next few weeks. Might solve your problems

Unplug the black injector plug at the head and clean with electric cleaner again, if problems keep happening get you’re fuel pressure checked out

i think it could be fuel related along - re-bleed the system and she starts and runs well and will go up to 70 nicely - turn her off and the problem comes back - will change the filter and pos fuel pump

Now Fixed!! it was air in the system - the filter housing had become pourous and snapped of the chassis when i went to remove the filter - i bought a GORE alloy fuel housing (which is a work of art) bleeded the fuel system and all is well again.
